I purposely didn't address this in my previous reply because I don't know tbh.
Breeder, who did the Loudness implementation originally said it complies to EBU R128 standard iirc, so I think reading related docs may be the best place to gather info.
E.g.

Sorry, can't help with more info.
edit:
The doc where the actual measurement process is described is

This is actually rather interesting, also for self-education.
The 'G' means the channels are weighted slightly differently.
